spool holder

You will need 4 ball bearings for assembling.
Can easily hold up to 2kg of filament for a smooth printing process.
The assembly is made out of four parts. 
You'll need to print “spoolholder-1” once and “spoolholder-2” twice.

dimension for ball bearings:
- outer diameter 22mm
- inner diameter 8mm
- thickness 7mm

I'd love to hear your experience with this design. 
If you have any feedback or input, feel free to comment.
